The song 'Apna Bombay Talkies' will have as many as 20 industry stalwarts and has been choreographed by Vaibhavi Merchant. "Vaibhavi has beautifully choreographed this number. There was a strict dress code for all the actors. All the men had to wear black tuxedos and the women wore gold outfits, designed by their own stylists," the statement said.

The song took over a month to be shot entirely as all the actors have independently shot for their parts. Over 20 singers have lent their voices to the actors. Some of the prominent singers are: Sunidhi Chauhan, Shaan, Kavita Krishnamoorthy, SP Balasubramaniam, Abhijeet, Kumar Sanu, Alka Yagnik, Mohit Chauhan, Sonu Nigam, Sudhesh Bhosle, Shreya Ghosal, Shilpa Rao, Udit Narayan and Sukhwinder Singh. "For the first time, 20 singers will be part of the same song.

The title track has been sung by some of the most reputed singers in the industry," the movie spokesperson said. 'Bombay Talkies' is an anthology of four short stories, each directed by a different filmmaker. The film that celebrates 100 years of cinema, will for the first time have four top directors from Bollywood, Dibakar Banerjee, Karan Johar, Zoya Akhtar and Anurag Kashyap - directing four movies.
